Abstract(in English) A high-temperature superconducting stripline (SL) transmit filter with shuttle-shape resonators is described that improves power handling and out-of-band rejection. A cascade quadruplet (CQ) design is used to produce a pair of attenuation poles for obtainint sharp cutoff characteristics. The filter had a four-pole SL CQ filter with shuttle-shape resonators (5.0-GHz center frequency and 100-MHz bandwidth). Simulation using the electromagnetic simulator showed that the out-of-band rejection was improved and frequency response of the filter was nearly symmetric. The maximum current density of the shuttle-shape filter was approximately 19% lower than that of a four-pole SL CQ filter with straight-line resonators. The filter was fabricated using YBa_2Cu_3O_7 thin films on an r-Al_2O_3 substrate. The filtering properties were clearly observed. From the result of the power-handling capability, the filter showed a liner property until 7.9W.
